CLAMPING DEVICE.

Application led June 6',

This invention relates to clamping devices and, while capable of use in other relations, is peculiarlyadapted for the purpose of securing to metal beams sheet-metal structural units ofthe general type shown in application No. 686,493 filed jointly by myself and Harry Gillett on January 16, 1924. The general object of the invention is to provide a simple, economical, and efficient means for showing the same secured 'to a beam byA means of clamps embodying my invention; Fig, 2 a planV view of a lport-ion of the construction shown in Fig. 1; Fig. 3 a detail in section corresponding to the line 3 3 of Fig. 1; Fig. 4a detail in perspective of one of the clamps; and Fig. 5 a view, similar to Fig. 3, showing a slightly modified form of the l,clamp as designed for use with an 1- beam. Y

Describing the various parts by reference characters, and in connection with Figs. Y1-4 inclusive, 1 denotes the web and 2 one of the flanges of a channel beam. ASupported by this beam is a` building-construction unit, the same comprising a metal sheet 3 having projecting downwardly therefrom hollow ribs 4, the said ribs being triangular insecltion and the tops of the ribs being substantially xclosed whereby the upper surface of the sheet 3 will'be substantially continuous or uninterrupted while the bottom of the sheet will be provided with triangular'ribs which are adapted to rest upon the topsof structural beams and' which lmay receivetherebetween fibrous insulating material.

The details of construction of the structuralv unit and the purposes and advantages of the same are fully set forth inthe aforesaid application, the clamping means shown herein being particularly .designed for securing units or sheets of this general character to the structural beams on which they are supported by the hollow ribs.

Each clamp is made of sheet metal and comprises generally an intermediate resilient spacing and supporting portion, tongues or 1924. Serial No. 718,213.-

securing'niembers projecting from one edge thereof for securing the same to the said sheet or unit, and beam-engagingy 'means projecting from opposite ends thereof. The

intermediate portion is bent or Ycorrugated topermit the beam-engagingportions or the member tobe sprung apart for kapplication y to a beam.

5 and. 5ZL denote the end portions, which portions are connected by an Vintermediate portion comprising acorrugated or -V-shaped central section or portion -6 and shorterlreverselycorrugated or V-shaped portions 7 located between the portion or section 6 and v the end portions 5 and 5a. The portions' 6 and 7 are of afwidth equal to the depth ofthe ribs et, whereby the sheet will be supported upon the-beam by means of thel ribs 4 and theA portions of the clamping members intermediate the ends 5 and'a. The end portion 5 is provided with a Vdownward extension 5' having a straight edge 5d which is adapted to engage the web 1 of a. channel beam. The Y tongues being located on the upper' edgefof K.

the clamping member-that is to say, the edge whichf and 5e.

vWith* theparts constructed and arranged as described, the clamping members will beslippedover t-he ends of the channel beams, with the projection 5e arranged beneath a iange 2 of a beam, springing the clamping inembersopen a suiicient distance to enabley the extensions 5? to engage the web 1 of-th'efv channel, the distance between the vedges 5d' and 5g being slightly less than the width of' the ilanges 2 whereby the clamping members,

when vappli-ed, will be retained in place friction, rIhe clamping members having been thus applied` the sheets 3 to the beams. Wvith a proper punch, the sheet will be driven down upon the tongues is lopposite theprojections V5c Zim are applied 8, which will puncture the sheet, after which the tongues will be bent overand flattened down, as shown in the drawing.

In Fig. 5 there is shown a modification of the form of clamping member shown in the preceding views-and which is adapted for use with I-beams and T-beams as well "as with channel beams, the web of the I-beam beingindicated at 9 and the lianges at one end being indicated at 1Q.y In this case, thev clamps will be of the same shape as shown in thepreceding views except that theedge 5d will be provided with a shallow notch 5h to receive the edge of the adjacent flange 10. In all other` respects, the clamping members to be used with the I-beam will `be identical with those which are used with the channel beams. y

Vhere it is desirable touse only a single formvof clamp, the one shown in Fig. 5 will be used,r since it is adaptedfor application to channel beams, ebeains and T-beains.

For convenience of description the sheets 3V are assumed to be applied to the tops of the structural beams, with the .clamping members resting on top of the beams and in j terposed between the same and the lower surfaces of the said sheets; and the terms upper and lower have been employed in the description and claims to set forth the relative positions ofthe parts but without vthereby limiting my invention to a construction wherein the positions of the beams and of the sheets may not be other than those specifically shown-and described herein.

By making the central portion G resilient and giving it a form of the character shown herein, the clampsand the sheet 3 secured thereto will be retained'by friction upon the.

lto engage beneath such flange and the other.

projection being arranged to engage the part of the beam opposite such flange, the intermediate portion rof such sheet metal body having an edge adapted torest upon the beam and an opposed edge adapted to engage such sheet, such'intermediate portion being deflected thereby 'to provide an eX- vtended bearing on said beam and place the'- end portions `of the clamp under tension,Y

the opposite edge of suchbody being provided with one or more integral tongues for fastening the sheet thereto.

, 2. As an article of manufacture, a clamp adapted to fastenV a metal sheetv to a strucf tural beam, said vclamp comprising a resili`" 'ent sheetmetal body having at each end .thereof aprojection, one of said projections being hooked to engage beneath a flange of a beam, and theother projection having a vertical face with a notch therein, whereby such second projection isl adapted to 'engage the web of-said beam, the intermediate por-v tion of such sheet metal body having an edge adapted to rest upon the beam and an op-l posed edge adapted to engage such sheet, such intermediate portion being deflected thereby to provide an extendedbearing on said beamcand place the end portions of thel clamp under tension, the opposite,v edgeof such body being providedwith one or more integral tonguesv for thereto.

3. As an article of manufacture,a clampv for securing a metal sheet to ak structural beam, saidvclamp compri-sing an intermediate spacing and supporting portion, means projecting upwardly from each end thereofA for securing the same to a metal sheet and beam engaging Vportions projectingjdown-` wardly therefrom for securing said. clamp to a. beam, said intermediate portion being bent to permit the beam engaging portions to be sprung apart for application to said beam.l

4L. AAs an article of manufacture, aclainp for securing a metal sheetA to a structuralv beam, said clamp comprising a body por-` tion'having corrugations therein andlbeing provided at. Opposite ends withcsecuring members-for securing` the same to a strip of j sheet metaland beam.. engaging Lmembers projecting downwardly from ythe opposite ends-thereof and adapted to be sprungk apart'- for application to said beam. -K f. 5. As an article of manufacture, a resilient sheet metalclamp forfastening 'a sheet` to a support,said clamp'comprising a body portion having one edgefadapted to engage a surface of said support; andbe'ing provided 4 with a pair of-r projections extending fromf such edge and :adapted tok engage` the voppo-A site sides of suchfsupport, 'the opposite edge,v 4of the said clampbeing'provided witlifmeans for attaching the same to the sheet tobe sofastened to the said support, the said body.

portion beingdeilected between the said projections whereby thev support-engaging projections maybesprung apart for application to such, support.
